find the base for the following items.

1.) 50 is 20% of what number?

2.) 50 is 20% of what number?

3.) 18 is 331⁄3% of what number?

4.) 4 is 1% of what number?

5.) 5% of what number is 90?

6.) 162⁄3% of what number is 72?

1. 50 is 20% of 250

Step-by-step explanation:

In order to find any of these, use the equation.

Number/Out of = %

Then plug in the values

50/x = .20

Then solve by cross multiplying

50 = .20x

250 = x

it has the same slope and a different y-intercept

hope this : )
